FLEECE-DIVIDING ATTACHMENT FOR CONDENSERS FOR CARDlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 227,671, dated May 18, 1880. Application filed October 23, 1879. Patented in Belgium August 19, 1879.

To all whom it may concern:

Be it known that I, JEAN SEBASTIEN B- LETTE, of Pepinster, in the Kingdom of Belgium, have invented a new and useful Fleece- Dividing Attachment for Condensers for Garding-Machines, which is fully set forth and described in the following specification.

This invention relates to dividing-condensers, or devices for severing into ribbons the fleece of wool or other similar material as it comes from the plain doffer of a carding-machine. Hitherto this has been effected in various ways, and among others by the employment of machinery consisting of rollers and several bands equal in number to the fleeceribbons to be obtained.

This invention consists in mechanism for I severing into ribbons the fleece as it comes from the doffer of a carding-machine, which mechanism consists in a single endless band passed over and crossed between two rollers, which I call dividing-rollers, and two smaller rollers, which I call driving-rollers, in the manner described, so as to form a series of bands disposed in figure 8 fashion, for the purpose described.

The dividing-rollers are placed between the two driving rollers, and may almost touch each other. Supposing the axis of the four rollers to be in the same vertical plane, the endless belt passes from the back of the upper dividing-roller to the front of the lower dividing-roller, and from there to the front of the lower driving-roller after having been twisted one hundred and eighty degrees. Passing under the' lower driving-roller to the back of the latter, and then to the back of the lower dividing-roller, it is carried to the front of the upper dividing-roller, having during its travel been shifted sidewise for about the width of the belt, so that the descending and the ascending parts of the belt cross each other between the dividing-rollers without twisting. From the front of the upper dividing-roller the belt ascends to the front of the upper driving-roller after having again been twisted one hundred and eighty degrees, and then it passes over the upper driving-roller again to the back of the upper dividing-roller, where its plane of motion is about two beltwidths apart from the plane in which it started.

In continuing this mode of motion the belt passes repeatedly over the different rollers, continually shifting its plane of motion, until it arrives at the end of the upper driving-roller, from where it is carried over two oblique guidepulleys to the opposite end of the upper driving-roller, and recommences its down motion. In passing the point where the ascending and descending portions of the belt cross each other the fleece is divided into ribbons having the breadth of the belt, each ribbon adhering to the inner side of the belt, which is afterward turned outside in passing from the dividing-roller to the driving-roller, so as to present the fleece ,to revolving rubbers which take it off the belt.

All parts of the endless band pass successively and rapidly on all parts of the rollers, and if some parts of the band are of different breadths from others they cause no difierence in the slivers.

In the accompanying drawings, in which similar letters of reference indicate like parts, Figure 1 is a side or end view, showing the new device fixed in position with reference to the doffer X and the rubbers Gr of a carding- Inachine. Fig. 2 is a plan of part of the device; Fig. 3, a front sectional elevation of same, looking from right to left; and Fig. 4, a sectional back view.

E is the endless band in one piece, B and O the dividing-rollers, and D D the driving-rollers. F are pulleys or carrying-rollers; H, the fleece to be divided to form slivers. In action the band E is wound in figure 8fashion between the dividing and driving rollers, and touches.

on its way the rubber G. The fleece passing between the dividing-rollers is divided by the band running in opposite directions, which takes two fleece-ribbons, one downward and the other upward. These fleece-ribbons are formed on the insides of the band; but by the twisting of said band the ribbons come outside and in contact with the rubbers, by which they are taken and formed into slivers.

The various parts of the machine shown in Fig. 1 are driven as follows: The belt 6 drives the pulley j, having on its axis a toothed pinion, which gears into the large spur-wheel K, keyed. on the shaft of the lower dividing-roller B. A spur-wheel on the axis of the dividingroller B drives a like spur-wheel on the axis of the dividing roller 0. These two spurwheels drive the rubbers G by means of intermediate spur-wheels, D, gearing into pinions placed at the end of the rubbers. L is a spurwheel mounted on the axis of the roller B, and driving the doft'er X by means of an intermediate spur-wheel, M. N is the drivingband for the draw-rollers P, and is driven by a pulley on the axis of the roller B.

I claim- The mechanism described for severing woolen fleece or similar materials into ribbons, said mechanism consisting of two dividing-rollers ing witnesses.
